Geology of the Cedar Hills, Utah
S.L. Schoff
1951, Geological Society of America Bulletin (62)-619
The Cedar Hills, an area of about 320 square miles in central Utah between the northern end of the Wasatch Plateau and the southern end of the Wasatch Mountains, form the boundary zone between the Colorado plateaus and the Great Basin. The oldest exposed rocks are Carboniferous, but most of...
Preliminary report on the stratigraphy and structure of the Shaviovik and upper Sagavanirktok Rivers area, Alaska
A. Samuel Keller, Robert L. Detterman
1951, Geological Investigations, Naval Petroleum Reserve No. 4, Alaska 36
During the 1951 field season, U. S. Geological Survey Navy Oil Unit party 1 conducted stratigraphic and structural studies of the rocks in the area between the westernmost fork of the Shaviovik River and the East Kuparuk River. This area is drained by the Sagavanirktok River and its major tributaries;...
Interpretation of aeromagnetic maps
V. Vacquier, Nelson Clarence Steenland, R.G. Henderson, Isadore Zietz
1951, Memoir of the Geological Society of America (47) 1-150
No abstract available. ...
Geologic guides to prospecting for carnotite deposits on the Colorado Plateau
Doris H. Blackman Weir
1951, Trace Elements Investigations 119
This report describes the geologic features that can be used to appraise the favorability of ground in guiding diamond-drill exploration for carnotite deposits in the Upper Jurassic Morrison formation on the Colorado Plateau. It is based on a statistical study of the geologic logs of about 2,500 holes drilled...
Older Precambrian structure in Arizona
Charles A. Anderson
1951, Geological Society of America Bulletin (62) 1331-1346
The older Precambrian rocks of Arizona include the Vishnu, Yavapai, and Pinal schists, all overlain unconformably by nonmetamorphosed younger Precambrian rocks. The older Precambrian schists, unnamed gneisses, and associated granitic masses crop out in many of the mountain ranges southwest of the Colorado plateau. The stratigraphy and structure of the schists can be unraveled to some extent by detailed mapping, and work now in progress by...
Geologic history of sea water: An attempt to state the problem
William W. Rubey
1951, Geological Society of America Bulletin (62) 1111-1148
Paleontology and biochemistry together may yield fairly definite information, eventually, about the paleochemistry of sea water and atmosphere. Several less conclusive lines of evidence now available suggest that the composition of both sea water and atmosphere may have varied somewhat during the past; but the geologic record indicates that these...
Report of the Committee on Ground Water, 1949–1950
S.W. Lohman
1951, Eos, Transactions, American Geophysical Union (32) 769-772
The present report concludes the duties of the above Committee, and the Chairman takes this opportunity to thank the members and others for their splendid cooperation during the triennium ended June 30, 1950. Another in the series of reports on hydrology and physiography of limestone terranes, by A. C. Swinnerton, is given as...
Geochemical techniques as applied in recent investigations in the Tintic District, Utah
H. T. Morris
1951, Economic Geology (46) 608-625
Field techniques for the rapid extraction and estimation of copper, lead, and zinc from altered rock are described, together with their application in the Tintic district, Utah. Either sulfuric acid or an acetic acid-ammonium acetate reagent is feasible as an extractant; but of these two, sulfuric acid is preferred. Data obtained by partial extraction methods show that zinc and...
